OPERATING INSTRUCTIONS FOR
USE WITH TRIMMER HEAD
WARNING:
Always wear eye protec-
tion. Never lean over the trimmer head. Rocks
or debris can ricochet or be thrown into eyes
and face and cause blindness or other serious
injury.
Before trimming, bring engine to a speed suffi-
cient to cut material to be trimmed.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will
be less likely to "weld" onto the spool.
Always release the throttle trigger and allow
the engine to return to idle speed when not
cutting.
To stop engine:
S Release the throttle trigger.
S Move the ON/OFF switch to the OFF
position.

TRIMMER LINE ADVANCE

The trimmer line will advance approximately 2
inches (5 cm) each time the bottom of the
trimmer head is tapped on the ground with the
engine running at full throttle.
The most efficient line length is the maximum
length allowed by the line limiter. Always keep
the shield in place when the tool is being oper-
ated.
To advance line:
S Operate the engine at full throttle.
S Hold the trimmer head parallel to and above
the grassy area.
S Tap the bottom of the trimmer head lightly on
Eye Protection
the ground one time. Approximately 2 inches
(5 cm) of line will be advanced with each tap.
Always tap the trimmer head on a grassy area.
Tapping on surfaces such as concrete or as-
phalt can cause excessive wear to the trimmer
head.If the line is worn down to 2 inches (5 cm)
or less, more than one tap will be required to ob-
tain the most efficient line length.
WARNING:
mm) diameter line. Other sizes of line will not
advance properly and can cause serious
injury. Do not use other materials such as
wire, string, rope, etc. Wire can break off dur-
ing cutting and become a dangerous missile
that can cause serious injury.
CUTTING METHODS
WARNING:
do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
which can damage the trimmer head, become
entangled in the line, or be thrown causing a
serious hazard.
S The tip of the line does the cutting. You will
achieve the best performance and minimum
line wear by not crowding the line into the
cutting area. The right and wrong ways are
shown below.
Tip of the line
does the cutting.
Right
S The line will easily remove grass and weeds
from around walls, fences, trees and flower
beds, but it also can cut the tender bark of
trees or shrubs and scar fences.
S For trimming or scalping, use less than full
throttle to increase line life and decrease head
wear, especially:
S During light duty cutting.
S Near objects around which the line can wrap
such as small posts, trees or fence wire.
S For mowing or sweeping, use full throttle for a
good clean job.
TRIMMING - - Hold the bottom of the trimmer
head about 3 inches (8 cm) above the ground
and at an angle. Allow only the tip of the line to
make contact. Do not force trimmer line into
work area.
